To Vall 'whom it may concern.'

Be it known that I, STANLEY W. HAYES, United States citizen, residing in the city of Richmond7 county of Wayne, Indiana, have invented the following described Improvements in Hand-'Operated Derails.

The invention provides an easily manufactured hand-operated sliding type derail, as distinguished from pivoted derails in'the operation of which the derail block is inverted, specially rsuited for installation under variant conditions of track without requiring the precise location on the ties required for other sliding derails and also adapted to be thrown -by hand with the same ease and promptness as the smaller types of pivoted derails. The invention consists, to these ends, in the organization of base and derailing members and theirrse'verall bearing elements according to the principles herein described and as exemplified in the accompanying drawings, whereiny Fig. l is a sidel elevation of the preferred form of the' invention in the closed position, Fig. 2 the same partly in section showing the derail block in the act of removal from the rail, l yFig'. 3 a partial end view of the forward bearing7 f y Fig. 4 a side elevation of the derail block in its movement towards the open position,

Fig. -the same in its fullyopen position,

Fig 6 a top plan of Fig. l,

Fig. 7 a rear elevation thereof.

The base member is composed of two upright side wall portions l unitedA by lower cross wall portions 2 and 3 provided with exterior spike flanges l by means of which it is spiked to two adjacent ties alongside the rail.V The derailing member comprises a body 5 and a derail block 6 bothl formed of a single casting recessed on its under side for lightness and formed with a central downwardly open cavity-7 serving as a handhold by means of which it is manually operated. Said cavity opens into the hollow interior of the derailing member so as to be self clearing of snow or water.

The body 5 of the derailing member is carried in the open space between the side walls of the base, in forward and rear bearings on which it is movable toward and from the rail by a generally horizontal movement. The rear bearing is formed by a central web or rib Sdepending from the rear part of (rig. e) and the derailing member and sliding by its lower curved edge upon a rounded bearing surface 9vformed on' the rear cross wall 3. The rib is coniined to this'bearing bythe two upstanding lugs l0 and 1l, one of which is undercut so as to overlie a rail l2 von the side of the rib to keep the rear part of the derailing member against upward displacement.v The forward bearing is formed by two laterally projecting studs'l which slide in grooves 14 formed in the inner faces of the walls of the base. 4W hen the derail block is moved from the position indicated in Fig.

5 toward the rail, the rib slides on its bearing 9 and the grooves 14 impart an upward inclination to the movement causing the block c to swing in a vertical arc (of increasing radius) rabout said rearbearing as a center and such upwardly directed movement continues until the block reaches the extreme limit of itshorizontal railward movement striking the side of the rail head, at which point each of-the studs'. 13 registers vertirailingV member, is however limited by the upper side of the grooves 14 which extend to the forward end of the base, the confines of such4 grooves thus serving to limit the vertical arc through which the derail block may swing. The vertical dimensionof theoffset spaces 15, however Vprovides an 'adequate vertical movement of the block when in its forward position suiiicient to'permitit to drop to a .firm bearing on the rail-head notwithstanding a considerable degree of misplacement of the guide box or base upon the ties, and the fact that the block swings about a pivotal axis furnished by the rear bearing which is at a considerable distance from the derail block (generally more than twice the distance of the pivot of common types of pivoted or swinging derails) insures that the bottom bearing surface of the derail ilo .Y videdI with aperforated locking Year 17, to

2 A Y y igieoaee block proper will rest practically ila-t upon the tread` suricace of the rail-head, thus providing a proper bearing tor the block notol; rib-form bearing herein described4 is also disclosed and claimed inl a copending application. v Y V Y The derail lbase above described is proreceive the hasp of a padlock7 which. when inserted will cooperate with the abutment surfaces 18 and 19 on the derailing member to lock it in either ont its extreme positions. It is also equipped with an attachment lug 20v 'for connection. to a target stand operated by the derail. ,These details areoptional but when the attachment lug is provided it is located suiiiciently close toY the level of the rear bearing so that the vertical `moveriient of the member will not tend to'movethe connecting rod 2l longitudinally thereby guarding lagainst any restraint to the `free descent oit 1he derail block upon thev derail or its upward' movement therefrom.r Y

Claims: l

1. A derail vcomprising a base and a derailing membery mounted thereon to be moved by hand substantially horizontally toward and from the-railv and supported upon forward and rear bearings, one of said bearings providing a, pivotal axis upon which said member may swing in a limited vertical arc and the other terminating in4 an abruptly offset space located to permit abrupt substantially vertical descent of. the derail block on its arrival the limit of its horizontal railavard movement.

2J A hand-operated derail comprisinga base and a derailing member mounted thereon uponV a rear bearing providing a pivotal axis on which said` member may Swingin a limited vertical -arc anda forward bearing havingy an abrupt and substantially vertical shoulder at the extreme positionV permitting abrupt descent of the derail block onitsy arrival at the limit of its horizontal railward movement, and preventing withdrawal oisaid member by a horizontally directed force.

3. A hand-operated derail comprising a base and a derailing member mounted thereon upon a rear sliding bearing'which provides a pivotal axis upon whichV said vmeniber may swing ina limited vertical arc, -and upon a forward sliding bearing having/an abruptly oiset space and abutmentsuriace at` its forward end permitting abrupt descent ot the derail blocl; on its arrival; at

the limit ot its horizontal railward movement and compelling the block to b enlifted i;

vertically before Ait can be Withdrawn lfromV the rail. Y 4i. A hand-operated derail comprising base andL a derailing member mounted theren to-move toward and from vthe rail and supported therein on forward and rear bearings, one oit said bearings having` an `abutment surface adapted to prevent Withdrawal ot the derail bya horizontally directed torce.V

5. A hand-operated derail comprising a base and a derailing member mountedftliereon on forward and rear bearings, one of said bearings being shaped to'compelmovement of the derailfbloclr' in an inclined1 path to a point above the rail and then sharply downward upon the rail-head, anda handhol-d formed on said member above-said .K

bearing. A

6. Anhand-operated derail comprisinga lsliding type derailingmember mounted `onV bearings on a base and carrying a derail block, said bearing being shaped to compel railward movement of saidinember first to a position above and in contact withthe side olf the rail-headjand;then.abruptly downward until the block seats on the rail tlead. 7. A hand-operated derail comprising a `base member and derailing member mounted thereon on a rear bearing constituted-by f a longitudinalV curvedl rib on one member sliding on the` other; member and a forward bearing groove shaped toy compel movement of the der ailing member first-Mtro a point dijrectly above the rail-head and; in--contact withsthe side thereoi. and' then abruptly downward onto the top of the rail-head,
